Single Disc Wafer Check Valve

A single disc wafer check valve is a type of check valve that uses a single disc to prevent backflow. The disc is typically made of a resilient material, such as rubber or EPDM, and is held in place by a spring. When the fluid flows in the forward direction, the disc is pushed open by the force of the flow. When the fluid flow stops, the spring closes the disc, preventing backflow.

Single disc wafer check valves are typically used in applications where the flow rate is relatively low and the pressure is not too high. They are also relatively inexpensive and easy to install. However, single disc wafer check valves can be prone to leakage if the disc is not properly seated.

Wafer Double Door Check Valve

A wafer double door check valve is a type of check valve that uses two discs to prevent backflow. The discs are typically made of a resilient material, such as rubber or EPDM, and are held in place by a spring. When the fluid flows in the forward direction, the discs are pushed open by the force of the flow. When the fluid flow stops, the spring closes the discs, preventing backflow.

Wafer double door check valves are typically used in applications where the flow rate is relatively high and the pressure is not too high. They are also relatively inexpensive and easy to install. However, wafer double door check valves can be prone to leakage if the discs are not properly seated.

Dual Plates Check Valve

A dual plates check valve is a type of check valve that uses two plates to prevent backflow. The plates are typically made of a metal, such as stainless steel or bronze, and are held in place by a spring. When the fluid flows in the forward direction, the plates are pushed open by the force of the flow. When the fluid flow stops, the spring closes the plates, preventing backflow.

Dual plates check valves are typically used in applications where the flow rate is very high and the pressure is high. They are also relatively expensive and difficult to install. However, dual plates check valves are very reliable and can withstand a lot of wear and tear.

Summary Of Check Valves For All Industries

The type of check valve that is best for a particular application will depend on the specific requirements of the application. Single disc wafer check valves are a good choice for applications where the flow rate is relatively low and the pressure is not too high. Wafer double door check valves are a good choice for applications where the flow rate is relatively high and the pressure is not too high. Dual plates check valves are a good choice for applications where the flow rate is very high and the pressure is high.
